Anthony Spinelli kingston nh, detonated explosive Tannerite at the party

A man has been charged with detonating 36 kilograms of explosives during a gender reveal party.

A US man who surrendered for a gender reveal party in New Hampshire that resulted in an explosion has been charged with disorderly conduct, police confirmed this week.

Anthony Spinelli surrendered to the Kingston Police Department after police allege he purchased and detonated approximately 36 kilograms of the explosive Tannerite at the party.

In April, an explosion occurred in a quarry near a concrete mixing business.

Tannerite is a target material used for firearms practice that also comes in gender-revealing varieties, according to police.

When Kingston police arrived, the partygoers admitted the explosion was part of a gender reveal party and later explained to a detective that they chose the quarry as a "safe location" to detonate the explosives.

However, the detonation caused tremors that some neighbours living near the quarry mistook for an earthquake.

Mr Spinelli was charged with disorderly conduct "due to the fact that he caused public alarm," police said in a statement. After a Kingston police investigation determined that the explosion did not result in "additional property damage," Mr Spinelli was charged with disorderly conduct "due to the fact that he caused public alarm."

Kingston police reported no injuries as a result of the explosion.

Other gender reveal parties have resulted in significant harm.

In February, a New York man who was about to become a father was killed when a device exploded.

A Michigan man was killed the same month when a "celebratory cannon" exploded.

And the El Dorado Fire in Southern California, a sprawling wildfire that scorched more than 10,500 acres in 2020, was caused by a pyrotechnic device used at a gender reveal party, according to fire officials at the time.
